Abstract

VistamaxxTM Performance Polymers are semicrystalline copolymers of propylene and ethylene. Produced using proprietary metallocene catalyst technology, VistamaxxTM polymers have a unique and uniform inter- and intramolecular composition and crystallinity distribution. The use of VistamaxxTM in rotomolded parts made from polypropylene-based materials improves key properties of the final article, such as impact performance and surface finish. Low impact strength usually limits the penetration of polypropylene in rotational molding, while VistamaxxTM polymers open up the window to compete with polyethylene-based rotomolded articles.

Abstract: VistamaxxTM Performance Polymers are semicrystalline copolymers of propylene and ethylene.

The use of VistamaxxTM in rotomolded parts made from polypropylene-based materials improves key properties of the final article, such as impact performance and surface finish. Low impact strength usually limits the penetration of polypropylene in rotational molding, while VistamaxxTM polymers open up the window to compete with polyethylene-based rotomolded articles.

Background

While it is desirable and advantageous to use polypropylene (PP) resins more extensively in rotational molding over polyethylene due to certain physical property improvements (stiffness, environmental stress crack resistance, heat deflection temperature…), impact strength is a key property for finished products made by rotational molding and remains deficient for polypropylene, restricting broad deployment in rotational molding.
